Description
Technical field
The invention belongs to medical equipment, be specifically related to a kind of 3 D stereo hard electronic hysteroscope system that utilizes many ccd array to carry out stereoscopic image reconstruct.
Prior art
Endoscope can be divided into plane endoscope and stereo endoscope with it by its planar or spatial image that forms images.
Present employed endoscope can also be divided into monocular and binocular by the quantity of the eyepiece of its use:
The first, monocular endoscope is by an optical system imaging; The doctor can directly use eyes to observe through the eyepiece end, but owing to be monocular instrumnent, can only obtain the image of an angle of object; Just as using single eyes to see the effect of object, object lacks third dimension and distance perspective.
The second, for stereo endoscope, use be the binocular structure, its endoscope distal end can be a camera lens or two camera lenses; The image of object is through two eyepiece outputs; The doctor can observe the stereoscopic image with the similar object of human eye through binocular, also can be through connecting particular processing main frame and display, through the processing of processing host; Can in display, show spatial image; But this image also is single angle, has certain limitation, the stereo laparoscope of this structure occurred using at present.But other applications also do not occur.
The doctor because monocular instrumnent becomes planar image, lacks spatial perception when using monocular endoscope to undergo surgery, so rely on doctor's technical merit.Though and the binocular stereo endoscope can obtain the stereoperception of similar eye-observation object; But because the limitation of human body cavity; The three-dimensional overall picture that can not reflect the whole surgery zone three-dimensionally; So the doctor will receive visual restriction when using existing scope to undergo surgery, for the cure rate of carrying out and improve disease of performing the operation certain restriction is arranged.
CCD (Charge-Coupled Device, charge-coupled image sensor) is a kind of important component part that can be used for stereoscopic camera.It is a kind of photosensitive semiconductor device, and the photosensitive unit on it converts the light that receives into the quantity of electric charge, and quantity of electric charge size is directly proportional with the incident light intensity.The technology of ccd image sensor is very ripe, can be spliced into the array of Any shape as required.Company of Fuji in 1999 releases super CCD technology, with the situation of common CCD equal area and photosensitive unit number under, its resolution raising 60%; Dynamic range improves 130%; Color reproducibility improves 40%, and energy consumption descends 40%, has further improved the function of CCD.The photosensitive unit size of CCD is constantly reducing; At present there has been the photosensitive unit size of report to be merely 0.5 μ m; Got into the submicron epoch, CCD will further develop round aspects such as high-resolution, high reading speed, low cost, microminiaturization, structure optimization, multispectral application and 3D photograph.But the area array CCD sensed image that the photosensitive unit of arranged constitutes.CCD is widely used in digital camera and the DV now, also in astronomical telescope, scanner and barcode reader, application is arranged simultaneously." Chang'e-2 " uses 96 line ccd array that same target is sampled, and all adds up signal at last.The target that very dark target, resolution are very high, " Chang'e-2 " can both break forth, and its resolution can reach 1 meter.
In the prior art, also the ccd array notion is not combined application with hysteroscope, therefore,, that many ccd array technology are extremely urgent with the bonded endoscopic technic of hysteroscope in order to obtain in the uterine cavity clearly 3 D stereoscopic image.
